The prince of the An family and the head of the An family were silent. Jiang Xingchen admitted defeat by occupying the Nangong family of Aliu Island this time. What if this matter was on him, would Chongming Island dare to send troops?

The answer is certain, you must send troops, otherwise where is the prestige? But so what about sending troops? Sixteen killer whales dominate the seas, and they will die if they go there. But for the sake of a reputation, they will not be scared to show their reputation.

What they didn't know was that this time Mandan Island did not admit defeat, but was fooled by Prince Nangong. The head of the Nangong family and the elders all thought that it was a good thing to contact Jiang Xingchen. If they got along well, they might get a steam engine. In this way, they did not make a move, but admitted the bet. But even so, the senior executives of Mandan Island were still very popular, but they asked Prince Nangong how to contact and prove it.

Prince Nangong has been very nervous these days. If Mr. Huang’s judgment is wrong and Jiang Xingchen does not agree to selling cement technology, everything will be exposed.

Fortunately, when the Wang family fleet left the sixth day, the sea eagle that Wang Zhicheng took away flew back and brought Jiang Xingchen's letter. Half the cement formula and the sale price were 100,000 stones. At this point, his heart was relieved.

Then Prince Nangong immediately ordered to send some people to guard Aliu Island and not let someone dig ore. He personally transported 100,000 yuan of stones to Linhai City and exchanged the other half of the recipe for it.

Jiang Xingchen's letter and half of the cement formula blocked the doubts on Mandan Island.

After six days and six nights of sailing, the Wang family fleet walked nearly 7,000 miles, and it was still two days away from Linhai City. It was much faster than when the young master of the Mu family went there.

The young master of the Mu family left the team halfway. They went to Shaman Island.

At this time, Jiang Xingchen was relieved. If everything went well, sorghum would be transported back before June 30th. Then before the end of July, strong-scented white wine could be brewed.

Although summer is not the time to brew white wine, he feels the temperature control pressure array, so of course he doesn't have to worry about temperature and humidity regulation.

As for selling the cement formula to Nangong Prince, he didn't even hesitate. This was for free, why don't you? Otherwise, would he buy it from the An family prince? In fact, after receiving a previous letter from Wang Zhicheng and seeing the negotiations with Nangong Prince, he knew that the other party must have bought papermaking from Chongming Island, so he was not afraid of Wang Zhicheng threatening with paper.

Since he can buy papermaking from Chongming Island, it is possible that he can also buy cement formulas. Of course, Jiang Xingchen must start first.

In addition, he also discovered that there must be other secrets on Pride Island, otherwise Prince Nangong would not be so careful. But he didn't care about any secrets, after all, it had nothing to do with him.

It is now early June, and the construction of the light rail highway has been underway for nearly a month. Compared with the road in the Curse Land, the progress of various forces is much slower. Even if the production scale of the light rail has been expanded in Minggang City, it is far from reaching demand. It can only slow down the construction speed. Waste labor and the consumption increase. There is nothing we can do about this.

"Spend more, spend more! These workers will be the main force in laying railways in the future, and they cannot be quit!" Jiang Xingchen sighed and prepared to get up to prepare the brewer.

Before he could go out, the old man walked in and he came back the day before yesterday with the ribs.

"Boy! What about the promised reward. I haven't forgotten this time, so please bring it up!" The old man stretched out his hand as soon as he entered the door.

Jiang Xingchen quipped and asked, "Reward. What reward?"

The old man became anxious when he heard this: "Boy, don't refuse to admit it. What did you say when you pulled me out of seclusion?"

"At that time, I meant to give you a reward!" Jiang Xingchen nodded and admitted.

"Then you won't give it to me. Do you know how tired you are when I went to Aliu Island by myself, I took tens of thousands of people to grab the island back..." The old man flew and gestured with his hands and feet.

"One person beats tens of thousands of people!" Jiang Xingchen was covered in black lines. This old guy was not reliable even to fool him!

"I want to give you a reward, but my new tea is half missing. What's going on?" Jiang Xingchen asked.

The old man blinked and said loudly: "I don't know what's going on with your tea leaves? Does it have anything to do with the reward?"

"You haven't admitted it yet, you've let it go before leaving!" Jiang Xingchen sneered.

The old man shook his head: "I don't know what you mean, I don't know what you mean! I didn't steal anyway!"

"Old guy, just be stubborn! You said you didn't steal it. After you left, I went to your yard to check it out. The tea that had brewed water was thrown in the corner. You don't admit it yet!"

"Impossible, I'll throw it all over the water...uh!" The old man's face changed halfway through his words, and the corners of his mouth twitched. This little soul was too sinister and accidentally fell into a trap again.

"Hmph!" Jiang Xingchen sneered: "You keep talking hard! I stole my tea and wanted to reward you, so I'm so beautiful!"

The old man drooped his face and whispered: "Then can you tell me what the reward is, so that I can enjoy listening to it!"

Jiang Xingchen continued to sneer: "Old guy, you are getting more and more thief! Listen to the rewards. If it is good, return the tea. If it is bad, I will not want it. Keep the tea! I'm right? Tell you, there is no way!"

The old man's forehead leaped and said loudly in anger: "Do you have a steam engine in your mind? It's so fast! I can die in one go!"

Jiang Xingchen laughed sinisterly and said to himself: "I don't have a steam engine in my mind, but there is something that is countless times stronger than a steam engine!"

"Forget it, forget it, I don't want the reward anymore. Anyway, the things you said are basically unreliable. What kind of painting round and square? I have practiced for so long hasn't worked. Why not enjoy the spring tea?" The old man said and turned around and walked out, but stopped when he arrived at the door, turned his head and laughed: "Boy, don't be proud, be careful about the tea left over you!"

"Old guy, you dare!" Jiang Xingchen's face also changed. It would be fine if his IQ crushed the old man, but if this old guy took action, there would be no way. It would be useless to hide it secretly.

Seeing Jiang Xingchen's angry look, the old man finally felt relieved, turned his head and ran away without a trace.

"This old guy is really unruly!" Jiang Xingchen breathed out and thought for a while. I can take the tea with him. How could he steal this... No, how can he put it on this hot day?

He was thinking about it when Xian Ning ran in from outside the yard with a roll of white paper in his hand.

"Why did you come just after running?" Jiang Xingchen couldn't help but be stunned. Xian Ning had never seen her like this before.

"Xingchen, I thought of it, I thought of it!" Xian Ning said panting as soon as he entered the room, with an unconcealed excitement on his face.

"What did you think of?" Jiang Xingchen asked, then immediately reacted and said in surprise: "You mean the braking system of a steam locomotive!"

"Yeah!" Xian Ning nodded vigorously.

"Tell me quickly!" Jiang Xingchen immediately pulled open the chair and asked Xianning to sit down. Then he sat next to Xianning himself.

Xianning opened the paper roll in his hand, and was covered with graphics and numerical notes.

"Look! We can add another cylinder to use steam to achieve the brakes. This is the entire structure, when it needs to slow down..."

Jiang Xingchen listened to Xianning's explanation and nodded repeatedly. The brake system was designed very reasonably and could not find any questions when looking at the drawings.

After Xianning finished the explanation, Jiang Xingchen raised his thumb: "A major breakthrough! Xianning, your long-term efforts have not been in vain. This braking system should be fine!"

Xian Ning laughed happily and said, "You can't be so sure, this is just a design concept. Whether it works in the end depends on the experimental results!"

Jiang Xingchen said: "In mid-August! The steel plant in Hongyuan City will be completed in mid-August, and parts and heavy rails can be produced immediately. Let's lay a section for experiments first!"

"Okay!" Xianning nodded and said, "If everything goes well, maybe the train can be officially put into operation before winter!"

"Hahaha... there is definitely no problem! If it can be put into operation before this winter, it will be completed within three years, and the old man will lose!" Jiang Xingchen laughed.

Xianning shook his head. Sometimes Jiang Xingchen is really like a child. The opening of the train is of great significance, but he is thinking about making a bet with the old man.

"By the way, Xian Ning, you have been busy for a long time. Let's take a break in the past two months!" Jiang Xingchen said.

"We can't rest now. The locomotive we designed to drive four pairs of wheels, and the steam engine needs to drive five cylinders. This requires a higher temperature and the internal pressure the boiler bears. New alloys must be studied to make the boiler."

Jiang Xingchen frowned. The first train that appeared in his previous life should not be that complicated. The steam locomotive they are studying now seems to be a bit super advanced!

"Xingchen, is there any problem?" Xianning asked when she saw Jiang Xingchen frowning.

"I'm just worried about your physical condition!" Jiang Xingchen said.

"It's okay, we are already familiar with the research of alloys, so we shouldn't be that tired... By the way, there is another thing! I'm afraid I can't take too much time, so you should think about physics and chemistry!" Xianning said.

"Okay! I'll try my best to make time! But these two things are really not easy to do!" Jiang Xingchen said with a smile.

"There are still things that are difficult to make for you?" Xian Ning smiled and teased, then stood up and said, "Okay, I'll go back first!"

"Xian Ning!" Jiang Xingchen called her and said, "Don't go back today!"

"Ah?" Xian Ning was stunned at the time, then she seemed to have rouge on her face and said coquettishly: "What are you talking about?"

When Jiang Xingchen saw Xian Ning's reaction, he immediately understood that he had a mistake in his tongue and hurriedly said, "Don't get me wrong. I mean that today's steam locomotive breakthroughs are made. Let's celebrate and let you stay here for dinner. I cook myself... It's not that meaning!"

"You still said it!" (To be continued...)
